IMPROVEMENT IN. GANG-FLOWS.

Specification forming vpart of Letters Patent No. 41,449, dated February2,1864.

To all whom it may concern:

Be it known thatLMARsHALL SATTLEY, of Taylorsville, in the county ofChristian, State of Illinois, have invented certain new and usefulImprovementsinGang-Plows 5 and Ido here by declare the following to be afull and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l is a rear view cfa gang-plow illus- Fig. 2 is a verticallongitudinal section at x ,Fig. l, looking toward the left. Fig. 3 is asection in the same plane, looking toward the right. Fig. 4 is avertical longitudinal section thereof at y y, Fig. l. Fig. Fig.5 is aplan of aportion of the frame, illustrating the mode of adjusting thetongue. Fig. 6 is a side elevation of a device for securing andadjusting the wheels. Fig.7 is avertical section thereof at e z, Fig. 6.Fig. 8 is a plan of the same.

Similar letters of reference indicate corresponding parts in the severalviews.

The subject of myinvention is an implement having two or'more plowsmountedina single beam extended in width for this purpose and adapted tolbe raised or lowered at will by a crank and lever, or theirequivalents.

The invention further consistsin certain devices for bracing the plowslongitudinally and laterally and adjustingtheir pitch or inclination, adevice for securing the tongue at any angle horizontally, and a devicefor setting the frame up or down on the wheels.

In order that others .skilled in the art to which my inventionapporta-ins may be enabled to fully understand and use the same, I willproceed to describe its construction and operation.

A represents the main frame of the implement, attached to an axle, B,which is provided at each end with a flange, C C, sliding in dovetailedplates D D, the edges d of which clasp the iianges G of the axle, inmanner clearly shown in Fig. 8, so as to prevent mo` tion in any but avertical direction.

Fromthe plates D project stud-shafts E E,

y upon which the conveying-wheels'F F are mounted. The adjustment of theaxle up or down may be effected either by hand-screws G Gr, swiveled attheir lower ends to the axle and threaded above in horizontal lugs H H,pro jecting inward from the plates D,or it may be 'secured in anydesired position by means of keys I, passed through elongatedperforations in the plates C and D, and turned to keep them from comingout. v

K represents a beam formed of a flat plank of sufficient width to carrytwo plows, L L, the standards M M of which may occupy suitable mortisesor be bolted directly to the edges of the beam, and are provided withlateral braces N N, projecting inwardly and secured in mortises near thecenter of the beam.

O O arelongitudinal braces, attached at their lower ends to thestandards M, and projecting forward and upward therefrom to the sides ofthe beam,when they are held by set-screws P, which occupy vertical slotsin the braces, so that the plows may be set on any desired angle orpitch'.

B R represent draft-chains, attached at their rear ends to the braces Oor standards M, and at their front ends to hooks fr r on the axle B, insuch position that4 they will be slack in the elevated position ot' thebeam and plows, but will be drawn tight by lowering the plows to theirworking position.

The elevation of the beam to raise the plows out of the ground and adaptthe implement to be transported from plane to plane is eected by acrank, S, journaled to the under side ot' the beam. This crank is turnedby means of a lever, T, having a motion of about ninety degrees within aloop, u, and held in any position by means of a segment-rack orperforated plate, U, in order to secure the plows at any desiredelevation. The horizontality of the beamv at all heights is preservedby'means of jointed rods V, by which its forward end is connected to theaxle B. A crank may be substituted for these rods, if preferred; orpointed rods may take the place of the crank already described.

The tongueW is attached to the front of the frame by two bolts, w w, oneof which, when its nut is loosened for this purpose,works in a slot inthe frame, so as to permit the tongue to be adjusted laterally in eitherdirection, when it may be again secured by turning down the nut.

f X represents the drivers seat.

Having thus described myinvcntiomwhatl bly to the axle B, and adapted tobe drawn claim as new therein, and desire to secure by Atight-bylowering the plows to their Working Letters Patent, is position.
